What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: GCL NT12R/48GDF-460W or GCL GCL-NT12R/54GDF-525?
According to our database: GCL GCL-NT12R/54GDF-525 has higher module efficiency (23.60% vs 23.02%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of GCL NT12R/48GDF-460W and GCL GCL-NT12R/54GDF-525?
GCL NT12R/48GDF-460 W has a module efficiency of 23.02%, while GCL GCL-NT12R/54GDF-525 is 23.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does GCL NT12R/48GDF-460W use vs GCL GCL-NT12R/54GDF-525?
GCL NT12R/48GDF-460 W uses TOPCon cells; GCL GCL-NT12R/54GDF-525 uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on GCL NT12R/48GDF-460W and GCL GCL-NT12R/54GDF-525?
GCL NT12R/48GDF-460 W has a 30 years power warranty; GCL GCL-NT12R/54GDF-525 has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.
Are GCL NT12R/48GDF-460W and GCL GCL-NT12R/54GDF-525 bifacial panels?
Both GCL NT12R/48GDF-460 W and GCL GCL-NT12R/54GDF-525 are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
